CLARINET BARREL.

Specification of Letters Patent. Pajtel'ltd H1351 23, 1922,

Application filed July 5, 1921. Serial No. 482,317.

T 0 @ZZ whom t may concern.'

Be it known that I, ALFRED J. SINCLAIE, a citizen of the United States, residing at Dayton, in the county of Montgomery and State oit Ohio, have invented certain new and useful Improvements lin Clarinet Barrels, of which the following is a specification, reference being had therein -to the accompanying drawing.

This invention relates to a clarinet barrel or the like. l

In a clarinet the body lof the instrument is connected with the mouth piece by a con` necting member, commonly known as 'the barrel, which is provided with a longitudinal bore, enlarged at one end to receive the reduced end ofthe mouth piece and enlarged at the other end to receive the reduced end of the instrument. Vhen the reduced end or' the instrument has been inserted in the barrel as far as it will go the end of the re` duced portion thereof will engage the shoulder at the inner end of the recess or enlarged portion of the bore and acontinuous pas sageway of uniform diameter will be provided. However, in practice it is frequently desirable to adjust the barrel lengthwise oi the instrument for the purpose of tuning the instrument and when this` is done the end of the instrument is withdrawn from the shoulder and an annular cavity, or lateral pocket, is formed, which is in open communication with the bore, or passageway for the air and which not only seriously affects the tone of the instrument but collects saliva' and is otherwise objectionable. It has beenvproposed to remedy this in 4.various ways, as by inserting washers in the recess, but this is objectionable in operation and is not satis-f lactory in its results, and the player usually endeavors to correct thefaults in the tone with his lips.

The object of the present invention is to provide a barrel which can be adjusted on the instrument without destroying the uniformity of the bore or passageway through the barrel.

A further object of the invention is to pro vide abarrel 'of this kind in which the cavity, or pocket, between the end of the instrument j and shoulder at the base of the recess will be automatically closed when the barrel is adjusted on the instrument.

Other objects of the invention will appear as the device `is described in detail.

In the accompanying drawings Fig. l is a longitudinal sectional view taken through a barrel embodying my invention, showing the mouth piece andafportion of the instrument connected therewith; Fig. 2 is a side elevation, partly in section, of a barrel embodying my invention; Fig; 3 is a section taken on the line 3*3 of Fig. l; Fig. l is a section taken on the line 4-4 ot' Fig. l; Fig. 5 is a section taken on the line 5 5 oit Fig. l; andFig. 6 is a detail of the slidable tube. In these drawings I have illustrated one embodiment ot.' my invention and have shown the same as applied to a clarinet of a standard,` construction. however, that this particular embodiment oi the invention has been chosen for the purpose of illustration only and that the invention may take various forms and may be applied tov instruments of various kinds.

In the Jform of the invention here illus` trated I have shown the same as applied to a clarinet, a portion `oit which is indicated by the referencenumeral l and has its upper end reduced, as shown at 2, to enter the recess 8 in the barrel 4. j The barrel s provided with a longitudinal bore, or passage, 5, which is enlarged in its lower endto form the recess 3 into which the reduced end 2 of the instrument extends. The reduced end ot the instrument is provided Vwith the usual cork insert 6 which serves to form a tight joint between the barrel and the instrument and to hold the barrel in its adjusted positions on the instrument. At its upper end the bore 5 ofthe barrel is also enlarged to receive the reduced end portionvof theinouth piece 7, which is of ordinary construction; The bore 5 and the enlarged end portion, or recess, 3 thereof arepreterably lined with metal and, as here shown, the liner lll for the bore and the recess is formed in a single piece but this is immaterial and the liner, if used, may be of any suitable character. Themain portion of the bore through the barrel, as shown at 5, is made of a diameter slightly larger than the bore of the instrument end and there is mounted in this borea thin metal tube 8 the inner diameter of which is substantially equal to the bore of the instrument end. This tube is slidably mounted in the bore 5 and means are provided for maintaining the end thereof in contact with the instrument end at all times, thus causing the tube to bridge the ocket which would otherwise be a v formed inthe recess when the barrel 1s 'adjusted away from the instrument end. This It will be understood,

lOO`

may be arcoinplished in vaiious ways but, as here shown` @l have provided the outer end o l the tube o with a laterally MiemingV ilange i) which is slidably mounted in the enlarged portion olf the bore, or recess, and is acted upon by a spring` l() conlined between the same and the shoulder at the inner end ot the recess. t will be apparent, therefore, that the spring,l will tend. at all times to move the tube toward the instrument end. and it the barrel is moved away trom the instrument end the tube will be maintained in engageh ment therewith and a passageway ot unitorni diameter provided at all times. The barrel is preferably provided with a shout der ll. forming a. recess l2 in which 'he spring,` seated. llfhen the barrel is moved toward the instrument end to the limit olf iiior-..riieiit the llange l) will engage the shoulder 1l andthe spring will be conlined wholly within the recess 12, thus positively limiting the movement ot the barrel and avoiding any possibility ot the spring' being,` disar` ranged. rl`he metal ot the tube 8 is very thin so that it. offers practically no obstruction to, or interlferenee with, the passage of the air through the passageway, the tube being shown in the drawings as ot an exaggerated thickness. The 'flange 9 preferably :lits snugly within the recess 3 so as to liorm an air `tight joint. Any suitable means may be provided to prevent the tube S being forced out ot the barrel by the spring when the bar` rel is removed from the instrument. In the present construction, this is accomplished by terminating` the liner 14: a short distance from the lower end ot the barrel and inserting` therein a collar, or a short liner, 13, the inner diameter of which is slightly less than the diameter et the liner and which. there` tore, forms a narrow shoulder which is sul'licient to check the outward movement ol2 the AFlange and tube. The difference in the dia` meters et the liner and the collar 113 is very slight and need not be more than two-thorn san dths olf an inch. (lonsetniently, it does not interfere with the insertion oli the instru` ment end in the barrel. as the cork Ainsert G Ywill readily accommodate itsel'lA to this slightly reduced diameter.

l he barrel in its outward appearance and `eneial Vcharac is verj7 similar to the ordiand it can be applied to any narybarrel tandard instrument in the same manner Ahat .-Tin'tlier. the operation oit the tube is wholly ment end without action ot any kind on the part ot the player, who adjusts the barrel in the saine manner as he would adjust the ordii'iary barrel.

While l have shown and described one @unit/)dir it ot my invention I wish it to be understood that l do not desire to be limited 1,41e,see

to the details 'ther/col as various nnnlitieations ina Y ocrur to a person skilled in the will be obvious that the tube might hc interposed between any two parts ol" the instrununit which are adjustable in the manner set 'ltorth, as, tor example, between the barrel and the mouth piece, in which event the mouthpiece would have, so tar as the present invention is concerned, the same functions as the instrument end and would coact with the tube in the same manner; or the tube may be mounted in the mouth piece r eli when the mouth piece is mounted lif en the instrument end.
